Umm this is a hard one cuz most women have options....may not be viable options, but they have options.
But some women highly value looks and want a man who is very attractive let alone sexually attractive to them. Key to finding a female simp is to be attractive, and work on ur grooming and body. Keep a fresh cut and dress nice. Work out that body to get it right.
U may also need to consider obese, homely, unattractive, older women who have something (money, gainfully employed, material possessions, etc.) to bring to table so she able to simp. Also, u may need to find women who are desperate, vulnerable, needy, low self esteem having, damaged, etc and I say this because most normal women don't have to simp cuz there so many thirsty men....so u gotta be really attractive and get into her mind and emotions for her to wanna do that. She gotta really like u.
